Vince Young shaky in preseason debut

Vince Young was the Titans' starting QB a year ago. Now, he's fighting for the backup job. Young took the field in the second quarter and four plays later he threw an interception. But Young regrouped, and just before halftime, the fourth-year veteran threw a perfect pass to WR Paul Williams in the corner of the end zone that put the Titans up, 21-3. Young played one more series in the third quarter and finished 5-of-10 for 39 yards.
